OK so i built a PC in 2013
here are the specs:
CPU: i5 - 3350p 3.10GHz
RAM: 4GB 1333MHz
when i first built it it ran smooth as butter. it was fast and never ever hung and its CPU usage was below 10% and it executed all tasks perfectly. now over time its gotten sluggish. i have ran plenty of antivirus scans and there are no viruses on it. i have defragged it plenty of times too.
i used the CPU thermometer app and it reads my CPU temp at idol to be 98-100C now i know that is not normal. i removed and cleaned the heat sink fan from dust but still no improvement. and for no reason at all the CPU usage over time kept increasing and increasing along with the RAM. when this PC was new i have no problem with RAM it would almost NEVER go to 50% use let alone 80%. i don't know what happened to it.
can this be a software problem or a hardware one? i don't download any sketchy software and i certainly don't man handle my PC so why overtime is the performance of such a state of the art machine degrading?
